I have just completed the design of a course on Strategic Business Analysis.  The problem I have found is that many of the techniques covered could fit comfortably in either "Business and Finance" or "Computers and Technology".

When you visit the course catalogue, you find that you can multi-select topic areas to search for your course.  Yet in the setup for your course, you can only select a single category.

I would suggest that course designers have the option to select more than one topic area for a course at design-time so that potential students have an easier time finding the course when searching the catalogue.
